Don't be ashamed. There is no difference between them. :-)

I thought I found a bug and fixed it. It turns out that it wasn't a bug,
and my fix did nothing to the sound. So the soundcheck firmware is
exactly the same as the standard Rockbox firmware, except that the
maximum loudness setting is 1dB lower on the soundcheck firmware.
